Cognitive impairment affects many psychiatric patients, influences daily functioning, and should be an important treatment focus. Assessment of cognitive status is crucial in cognitive remediation studies. However, current test batteries have limitations. A new, online tool, the MyCognition Quotient (MyCQ), was developed to assess cognition within 30 min. We present the psychometric properties and aim to determine the validity of the MyCQ by comparing it with the Cambridge Neuropsychological Automated Test Battery (CANTAB).
Eighty-seven patients diagnosed with obsessive compulsive disorder, schizophrenia/schizoaffective disorder, or major depressive disorder were included. Patients completed both the MyCQ and CANTAB.
Our hypothesized domains of psychomotor speed, attention, episodic memory, working memory, and executive functioning were confirmed by principal component analysis. The MyCQ total score correlated highly with the CANTAB total score. The MyCQ domains of psychomotor speed, attention, and episodic memory showed moderate to high correlations with corresponding CANTAB domains. Working memory and executive functioning had limited divergent validity.
The MyCQ appears to be a promising instrument for assessing cognition online within a mixed psychiatric population. It is cost-efficient, easily administered, and usable in different psychiatric populations, which makes it a good candidate for both clinical and community studies.
认知障碍影响许多精神科患者，影响日常功能，应成为重要的治疗重点。认知状态的评估在认知矫正研究中至关重要。然而，目前的测试组合存在局限性。我们开发了一种新的在线工具——MyCognition Quotient（MyCQ），用于在 30 分钟内评估认知能力。我们介绍了心理计量学特性，并通过将其与剑桥神经心理自动化测试电池（CANTAB）进行比较，旨在确定 MyCQ 的有效性。
纳入 87 名被诊断为强迫症、精神分裂症/分裂情感障碍或重度抑郁症的患者。患者均完成了 MyCQ 和 CANTAB 测试。
我们假设的心理运动速度、注意力、情景记忆、工作记忆和执行功能领域通过主成分分析得到了证实。MyCQ 总分与 CANTAB 总分高度相关。心理运动速度、注意力和情景记忆的 MyCQ 领域与相应的 CANTAB 领域具有中度到高度相关性。工作记忆和执行功能的差异效度有限。
MyCQ 似乎是一种很有前途的在线评估混合精神科人群认知能力的工具。它具有成本效益、易于管理和可用于不同的精神科人群，这使其成为临床和社区研究的理想选择。
